Dad's in the hospital again

Well, this title is pretty much self-explanatory. My dad was having a lot of trouble breathing this morning and was unable to make it out of the house for his radiation treatment. He was really short of breath, and couldn't even make it to the door, much less out to the car.  I'm just waiting to hear something. They said it probably wouldn't be until sometime later today. Anyway, that's it for now. I'm holding it together.
